PATE/vrA-r mRNEYs United States Patent i WINDOW FRAME CONSTRUCTIONErnest B. Sullivan, Calgary, Alberta, Canada Application August 1o,195s, serial No. 527,526 s Claims. (cl. zii-11) My invention relates tonew and useful improvements in window frames and sliding windowstherefor, the principal object and essence of my invention being toprovide a window frame which can readily be set in place within the wallof the building, and which includes a continuous stop strip therearoundadapted to seal completely the frame to the wall opening.

A further object of my invention is to provide a frame in which thecross-sectional configuration of the four members making up the frame issimilar, thereby permitting the members to be mitred together at thecorners, thereby making an economical window frame.

Yet another object of my invention is to provide a device of thecharacter herewithin described which is particularly adapted for usewith horizontal sliding window sashes, it being only necessary to securethe rails to the frame whereupon the window sashes are mounted ready foruse.

A still further object of my invention is to provide a device of thecharacter herewithin described which includes a novel Vertical junctionbetween adjacent sliding sashes which not only is positive in action,but includes resilient means on each sash adapted to register one withthe other, thereby effecting an efficient vertical seal therebetween.

A yet further object of my invention is to provide a device of thecharacter herewith described which includes a relatively simple lock toprevent the windows being moved or opened by intruders and the like.

With the foregoing objects in view, and such other objects andadvantages as will become apparent to those skilled in the art to whichthis invention relates as this specification proceeds, my inventionconsists essentially in the arrangement and construction of parts all ashereinafter more particularly described, reference being had to theaccompanying drawings in which:

Figure 1 is a fragmentary, horizontal section of the junction betweentwo adjacent sliding sashes.

Figure 2 is a fragmentary vertical section of one of the sash railstogether with portions of an inner and outer sash in position.

Figure 3 is an enlarged fragmentary front elevation of the lock stopdevice.

Figure 4 is an enlarged fragmentary section of part of one of the windowsash frames showing an alternative method of securing the glasstherewithin.

Figure 5 is a fragmentary front elevation of part of my window frameshowing a portion of a sliding sash there- Within.

Figure 6 is a fragmentary cross-sectional view of one side member of theframe and window sashes, and is substantially a plan view of Figure 5.

Figure 7 is an enlarged fragmentary vertical section through the sillframe member of the frame, together with a pair of sash rails in situ,and showing the frame in position upon a part of the wall of thebuilding.

In the drawings like characters of reference indicate correspondingparts in the different gures.

2,791,004 Fatented May 7, 1957 Proceeding first to describe the windowframe collectively designated 1` and shown in Figures 5, 6 and 7, itwill be seen that it consists of a rectangular frame including a stillframe member 2, a top frame member 3 and a pair of side frame members 4,one of which only is shown.

The cross-sectional configuration of these members is best shown inFigures 6 and 7, and it will be seen that this 'ice cross-sectionalconfiguration is similar for all of the four.

sides of the frame. This not only simplifies manufacture, but permitsthe corner joints 5 to be mitred together, thus making a very strongsound frame construction. Each of the members 2, 3 and 4 are providedwith a relatively wide, open, rectangular recess 6 within the outersurface 7 and adjacent the inner edge 8 thereof. Also formed upon theouter surface of these members but adjacent the outer edge 9 thereof isa slot 1t) adapted to receive a planar metal strip 11 which constitutesa stop strip. These metal strips are provided with moisture repellingmaterial such as building paper 12 wrapped around the strip which isthen held within the slot 10 by friction. It will be seen from Figure 7that the stop strip 11 extends beyond the outer surface 7 of the memberand terminates at a point 13. Due to the symmetrical construction of theframe, the ends 14 of adjacent strips 1l, over-lap at the corners 15thereof, and may be joined together by spot welding 16 or similar means,thus forming a continuous stop strip around the entire window frame,which makes an efficient seal against the ingress of moisture.

A metal screed 17, having a right angular cross-sectional configuration,is adapted to be positioned within the recesses 6 so that one liange 18thereof bears against the inner surface 19 of the recess, and the otherflange 20 bears against the outer wall 21 of the recess, as clearlyshown in Figure 7. The flange 20 extends beyond the surface 7 of theframe members and terminates in a curved end Z2 which acts as aneiiicient plaster key for the interior finishing plaster 23.

Figures 5, 6 and 7 show details of the mounting of the frame within thewall opening, and it will be observed that a space 24 is providedbetween the members and the edges of the wall opening within whichinsulation 25 may be placed. Furthermore, exterior stucco 26 may beplaced on the outer wall thereby covering and sealing the stop strip 11.

Upon the sill frame member 2, a run-olf board 27 is secured, saidrun-olf board being adapted to carry a p'air of sash rails 28 withinwhich sliding sashes collectively designated 29 may run. Similar sashrails (not illustrated) are secured to the under surface of the topframe member 3 and the side edges of these sashes are adapted toregister within slots 30 formed within the side members 4 as shown inFigure 6. Figures 1 to 4 inclusive show details of the configuration andconstructi'on of the sash rails and the sliding sashes, Figure 2 showingthe cross-sectional configuration of the rail 28. In this embodiment,each rail consists of two pairs of side plates 31 mounted upon an11p-standing shoulder base 32 and secured together by bridging strip 33,it being understood that the entire rail is preferably extruded. Eachsliding sash 29 includes a base frame member 34, having a configurationshown in Figure 2 from which it will be seen that the flanges 35 areadapted to register upon each side of the base shoulder 32 and that thesash slides on a plastic runner 36 secured to and extending upwardlyfrom the shoulder 32.

The glass pane 37 is secured within the frame member 34 by means of larelatively hard compr-essible locking wedge 38 having barbs 39 engagingwithin corresponding grooves in the frame, said wedge 38 forcing theglass against a non-hardening semi-adhesive and sealing strip 40 Withinthe other side of the glass recess 41. Finally a exible locking bead 42is inserted thereby preventing v same are closed. In this embodiment,the vertical innery sides 44 of adjacent sashes are provided withmembers 45 having an off-set vertical flange 46 formed integrallytherewith, these anges overlying the centre` line 47 of the rails 28.`These off-standing flanges 4are adapted to engage one with the otherwhen the Windows are closed,

as clearly shown in Figure l, and in order to provide an cicient `sealtherebetween resilient `buffers 48 are set in the inner surfaces 49 ofthe flanges 46, said buffers adapted to engage one with `the fother whenthe windows are closed, thus sealing off this vertical junctioneffectively.

It is also desirable to prevent'the Windows from being opened byintruders and the like, and in this connection a shot bolt 50 isprovided within the lower sash frame member 34, said bolt having anoff-standing portion 51 extending through 1an aperture (not illustrated)in the member 34, and adapted to engage a recess 52 formed in the sidewall 31 of the rail. Therefore when in the down position, as shown inFigures 2 and 3, the window cannot be moved sideways at all until theportion 51 is rotated in the direction of arrow 53 to the position shownin phantom in Figure 2.

Finally it should be mentioned that the window frame 1 can be secured tothe wall opening by means of nails Vdifferent embodiments of same madewithin the spirit and scope of theclaims without departing from suchspirit and scope, it is intended that all matter contained in theaccompanying speciiication shall be interpreted as illustrative only andnot in a limiting sense.

3. The device according to claim 2, in which said metal screed is rightangular when viewed in cross-section, one ange of said screed adaptedIto register against the inner surface of said recess, the `other angeof said screed resting against the outer wall of said recess andextending therefrom, and a curved edge on said last-mentioned angeadapted to lact as a plaster key.
